I have an idea for Reshiram and Zekrom. The cave on route 4 called the Path of truth has nothing but dragon types in it, and has a stone tablet colored half white and half black, with a spherical indentation in the middle. This resembles a hole that a player could put the Dark or Light stonethat they would get from some future area into the hole to summon Reshiram or Zekrom.
